Trust is a key factor when it comes to making an agreement between parties in negotiation or conflict. Reaching minimal levels of trust when parties ignore one another’s reputation is a gradual process resulting of analyzing utterances and mutual actions. We present a model for trust mediation between two parties named balance of trust that represents the level of conjoint honesty and certainty between parties. We also use graphics to represent the balance of trust through a visual interface in a virtual mediator that attempts to persuade two strangers to trust each other in a competitive and excluding context. The persuasion mechanism depends directly on the interface design that shows both parties how far or close they are to reach optimal balance without compromising the asymmetry of the information. Results of exploratory experiments reveal that the interface reduces the time both parties take to cross the trust threshold, but, sometimes, it also constrains them due to the risks of being deceived. Experiments also showed some aspects of human morality that emerge with the possibility of deceiving or being deceived.
- Developing trust through interfaces of cooperative persuasion (In Spanish) Paper
Our proposal is that the balance of trust between two parties is determined by the balance between honesty and certainty of mutual expectations. We define these two conditions as:
- Honesty is the quality of saying or acting truthfully. The either sincere or misleading utterances or actions derive in honest or deceiving behaviors.
- Certainty is the set of expectations related to what the other party says or does. One could have false expectations when one trust false statements.
We compare the four intersecting subsets — honesty, dishonesty, true certainty and false certainty– and compute a numeric index that conveys how honest and certain were the parties.
This model of trust has been tested in videogames that explore the emergence of trust in competitive interactions. Please find the results here.
